This paper did sensitivity analysis about stable parameters of rock slope using finite element strength reduction method, and it also did theory analysis and numerical simulation using unloading rock mass mechanics, elastic-plastic theory during the unloading effect process of slope after excavation.

Application of cultivars stability parameter and high stable coefficient in the analysis of sugarcane regional trial in Yunnan;

The expression of stability parameter H is developed based on the stream function and axial velocity function of Newton helical flow in eccentric annuli with the inner and outer cylinders rotating simultaneously in this paper.

Using the method that is stability parameter,high stability coefficient,average of yield,coefficient of variation and coefficient of regression judged productivity and stability of 17 new maize varieties in Henan Maize Regional Trail in 2003.

The concept of steady-state parameters was put forward.

In the new scheme,Obukhov stability parameter is directly parameterized through bulk Richardson number,aerodynamic roughness length and heat roughness length,and thus the flux can be derived by using the universal functions of Hgstrm(1996)and Beljaars et al.

But parametric stability test shows that,among the eight consumption expenditure equations that comprise a whole demand system,only the equations for clothing,household facilities and services,transportations and communications,miscellaneous commodities and services,as well as cultural,educational and recreational articles and services have witnessed a local and temporary structural change.
